// echarts按需引入
// 引入 echarts 核心模块，核心模块提供了 echarts 使用必须要的接口。
import * as echarts from 'echarts/core'

// 引入图表类型，图表后缀都为 Chart
import { BarChart, LineChart, PieChart, FunnelChart, GaugeChart, MapChart, PictorialBarChart, EffectScatterChart } from 'echarts/charts'

// 引入提示框，标题，直角坐标系等组件，组件后缀都为 Component
import { TitleComponent, TooltipComponent, GridComponent, LegendComponent, ToolboxComponent } from 'echarts/components'

// 标签自动布局，全局过渡动画等特性
import { LabelLayout, UniversalTransition } from 'echarts/features'

// 引入 Canvas 渲染器，注意引入 CanvasRenderer 或者 SVGRenderer 是必须的一步
import { CanvasRenderer } from 'echarts/renderers'

// 将以上引入的组件使用use()方法注册
echarts.use([
    TitleComponent,
    TooltipComponent,
    GridComponent,
    LegendComponent,
    ToolboxComponent,
    BarChart,
    LineChart,
    PieChart,

    GaugeChart,
    MapChart,
    LabelLayout,
    UniversalTransition,
    CanvasRenderer,

])

// 导出
export default echarts
